BH Series bevel helical gearboxes are designed with a wide concept of modularity, which is accomplished by composing a structure of kits of the main sub-groups, giving rise to the different configurations of the final product, thus fulfilling the main application needs. On the other hand, modularity brings meaningful advantages for the distribution network, both in terms of timing for supplying the product to the end customer and in the optics of the optimization of warehouse investments.
